Refer to the exhibit. Which prefix does Router 1 use for traffic to Host A?

• 10.10.10.0/28

• 10.10.13.0/25

• 10.10.13.144/28

How does HSRP provide first hop redundancy?

• It load-balances traffic by assigning the same metric value to more than one route to the same destination m the IP routing table.

• It load-balances Layer 2 traffic along the path by flooding traffic out all interfaces configured with the same VLAN.

• It forwards multiple packets to the same destination over different routed links n the data path.

• It uses a shared virtual MAC and a virtual IP address to a group of routers that serve as the default gateway for hosts on a LAN.

Refer to the exhibit. Which password must an engineer use to enter the enable mode?

• adminadmin123

• default

• testing1234

• cisco123

• Configure the version of SSH.

• Configure VTY access.

• Create a user with a password.

• Assign a domain name.

Which attribute does a router use to select the best path when two or more different routes to the same destination exist from two different routing protocols?

• dual algorithm

• metric

• administrative distance

• hop count

Which statement about static and dynamic routes is true?

• Dynamic routes are manually configured by a network administrator, while static routes are automatically learned and adjusted by a routing protocol.

• Static routes are manually configured by a network administrator, while dynamic routes are automatically learned and adjusted by a routing protocol.

• Static routes tell the router how to forward packets to networks that are not directly connected, while dynamic routes tell the router how to forward packets to networks that are directly connected.

• Dynamic routes tell the router how to forward packets to networks that are not directly connected, while static routes tell the router how to forward packets to networks that are directly connected.

How does STP prevent forwarding loops at OSI Layer 2?

• TTL

• MAC address forwarding

• Collision avoidance

• Port blocking
